Chemical compound

Cerium(IV) fluoride is aninorganic compound with achemical formula CeF₄. It is a strong oxidant that appears as a white crystalline material. Cerium(IV) fluoride has an anhydrous form and a monohydrate form.^[2]

Production and properties

[edit]

Cerium(IV) fluoride can be produced by fluorinatingcerium(III) fluoride orcerium dioxide with fluorine gas at 500 °C^[3]

\mathrm {2\ CeF_{3}+F_{2}\longrightarrow 2\ CeF_{4}}

\mathrm {CeO_{2}+2\ F_{2}\longrightarrow CeF_{4}+O_{2}}

Its hydrated form (CeF₄·xH₂O, x≤1) can be produced by reacting 40%hydrofluoric acid andcerium(IV) sulfate solution at 90°C.^[4]

Cerium(IV) fluoride can dissolve inDMSO, and react to form the coordination complex [CeF₄(DMSO)₂].^[4]
